To all whom t may concern:

Be it known that I, ANDREW B. HYDE, a citizen of the United States, residing'in the borough of Manhattan, city, county, and State of New York, have invented an 1mrovement in Fountain Pens, of which the 'ollowing is a specification.

This invention relates to a fountain pen and more particularly to that type of fountain pen in which there is employed a reservoir to receive and hold an overflow or surplus of ink in order to prevent the ink from dropping from the pen and causing blots. I am aware that heretofore fountain pens have been provided with an excess or overflow ink reservoir and that in such structures there has been provided a wall enclosing the reservoir chamber beneath the pen. These structures,` however, have proved unsatisfactory because no adequate provision has been made for preventing the action of gravity from overcoming the adhesion of the overflow ink to the under surface of the pen and feeder and to the wall of the overfiowreservoir. The result is that often the overflow ink escapes from the overow reservoir through the space existing between the pen and the edges, and sides of the wall enclosing the chamber of the overiiow reservoir and makes a blot.

rlhe object of my invention is to overcome this diculty and in doing so l provide a means of preventing the action of gravitation from causing the ink to pass from the overiow reservoir and drop from the pen, thereby making a blot. ln carrying'out the invention to obtain the desired result Iemploy an overflow reservoir provided with a cover closing or substantially closing the ,same and conforming substantially to the inner or under surface of the pen. The surfaces of the cover co-act with the surface of the feeder, the under surface of the pen and the inner surface of the walls of the reservoir, thereby furnishing a sutlicient amount 0f surface to provide for adhesive action great enough to prevent the ink in the overow reservoir from passing out therefrom and dropping from the pen. The cover member furthermore is provided with an opening, parts' of which lie on both sides of the feeder beneath the nibs of the pen so as to permit the flow of ink from the feeder to the overflow reservoir when the ink flows too freely from the main reservoir of the pen and also to permit the ink to flow from the overow reservoir in the opposite direction to the nibs of the pen to supply the same with ink and clear the overflow of'ink, when the overflow of ink from the feeder has ceased.

The fountain pen madev in accordance with my invention preferably comprises a cylindrical or barrel member containing the main ink reservoir and'l a pen section is connected thereto and comprises a nozzle, a plug fitted in the nozzle and with which there is associated a pen, a feeder and suitable walls forming an overow reservoir and including a cover with an opening therein to which reference has hereinbefore been made and all of which will be hereinafter more particularly described.

In the drawing;

Fig. 6 is a longitudinal section illustratin the cap employed with the pen. l

Referring to the drawing it will be seen that the fountain pen made in accordance with this invention comprisesK a cylindrical or barrel member 10. rlhis, as is customary, is fitted with a pen section which includes a nozzle 11 connected to the end of the barrel by screw threads 12 in the usual manner. The pen section also includes a plug 13, a pen 14, a cover 18 and a feeder 21, which arev secured tothe nozzle 11 `by frictional contact. The overflow reservoir is indicated at 15 and the walls'16 thereof are connected to or made integral with the plug member and in a suitable position are provided with a slot 17, the purpose of which will be hereinafter indicated.

The reservoir also is provided with a cover -18 which is made to t the said walls so as to close or substantially close the reservoir, and the upper surface of the cover is made to conform generally to the inner surface of the pen. At or adjacent to its outerend parts illus- `the cover is provided with a hole or opening 19 and in the upper surface of the cover extending longitudinally of the samethere is a groove 2() to receive the feeder 21 in which there is also a longitudinal groove 22 through which the ink passes from the reservoir in the cylindrical or barrel member of the pen. As is customary the plug 13 is provided with a vent or passage 23 and as illustrated in the drawing the cover may be secured in position upon the plug and upon the edges of the reservoir walls by suitable. pins 24, or otherwise. As will be also noted in the drawing the cover 18 at its outer end preferably fits and lies within vthe end portion of the walls forming the overflow reservoir as is also the case with the feeder 21 and in addition to the pins 2d and 25 the cover may be suitably connected to the walls` of theA reservoir by being cemented or otherwise connected thereto. llihen there is ink in the overflow reservoir 15, and the fountain pen is lying in a horizontal position or held in a perpendicular position in the pocket, such ink may ooze out through thepoint of contact of the cover 18 with the edge of the reservoir wall and thus soil both the cap 26 and the nozzle 11. By cementing the cover 18 to the edge of the reservoir wall, the point of contact is made impervious to the passage of ink; and the soiling of the cap and nozzle is thereby prevented.

ln the use of the pen, as hereinbefore de scribed, the ink from the main reservoir 10', as is customary, flows therefrom through the feeder to the pen where it may be used. lin Y the event of the ink flowing too freely the surplus ink, as will be understood, passes through the hole 19 into the overflow reservoir, and the hole 19 made in the cover for this purpose is preferably as narrow as is compatible with the efficient operation of the pen. rlhis hole, however, may be of any desired length. rlllhe air necessary to replace the ink as withdrawn from the main reservoir 10 passes through the slot 17 into the overflow ink reservoir 15 and through the vent 23 to the main reservoir and when the ink flows too freely the surplus passes through the opening 19 in the cover 18 to the overflow /reservoir 15. r1"his overflow ink adheres to the walls of the overflow reservoir, to the inner surface of the cover 18, to the outer surface of the cover 18, to the outer surface of the feeder 21, and to the under surface of the pen 14; and these adhesions are sufficient to prevent the action of gravity from drawing the ink out of the overflow reservoir and making a blot. Likewise when the overflow of ink fromthe feeder 21 has ceased, the inlr in the overflow reservoir 15 passes in the opposite direction through the. opening 19 in the cover 18 to the nibs of the pen 14 in order to supply the pen with ink for writing and clear the overflow reservoir of surplus ink. lifanifestly also any ink which passes through the vent 23 in the plug mageos is contained in the overflow reservoir and may pass freni the same through the opening 19 to supply the pen with ink, in which case the overflow reservoir is cleared of this ink in the same manner as the surplus ink from the feeder is taken care of.

l/lhile l have shown and described the feeder as associated with the outer surface of the cover of the reservoir it will be understood that this member may be otherwise disposed and the pen ,made to operate to equally good advantage. lFor example, the feeder member may be made an integral part of the cover, or the feeder may be caused to pass through the cover, or the feeder might be made to lie on the inner side of the cover without departing from the nat-ure and spirit of the invention.

By reference to Fig. 6 it will be seen that the pen may be provided with a cap indicated at 26 and adapted to be connected by suitable screw threads or otherwise'with the nozzle 11 so as to cover the pen section when the pen is not in use.
